the CM-12 is properly installed and operates correctly.
MOUNTING
1. The CM-12 is correctly and securely fastened to
the ceiling.
2. It is mounted where it will not interfere with normal
occupant traffic.
3. Unit is properly oriented for good air circulation.
ASSEMBLY AND OPERATION
1. Be sure that the prefilter, primary particle filter and
carbon filters are all properly installed.
2. Be certain the electrical junction box cover is
reinstalled.
3. Turn the air cleaner on using the knob near the
intake grille. Make sure that the blower energizes
and creates airflow into the intake grille.
MAINTENANCE

the filters.
2. When servicing the air cleaner, stand on a
stable work platform or ladder.
FREQUENCY OF FILTER MAINTENANCE
The MiracleAir™ Model CM-12 is designed to have a
very long filter maintenance interval. This is accom-
plished because of the large volume of media used in
both the particle filter and the odor/vapor module. See
the Specifications section for details.
The exact maintenance interval is determined by the
specific application of the MiracleAir™ unit. In an
office application, the prefilter could require cleaning
every 2-3 months. The primary particle filter may last
1-2 years and the odor/vapor filters should be replaced
every 6 to 9 months in the standard unit.
Because of the different variables with each
application, it is recommended that the prefilter be
inspected every two weeks during the first couple of
months of operation. When there is a noticeable
accumulation of dust and dirt, clean the filter. After
inspecting the unit for a one or two month time period,
you will have established the proper cleaning interval
for the prefilter. When the MiracleAir™ unit no longer
removes odors from the air, it is time to replace the
disposable filters within the odor/vapor modules.
When there is a noticeable reduction in airflow with the
prefilter clean, it is time to replace the primary particle
filter. It is a good idea to keep track of how long a
period of time the primary particle filter and odor/vapor
filters lasted so that you can anticipate how long the
new filters will last. The first filters will likely require
changing sooner than subsequent filters due to dust
that may have settled in areas with poor air circulation
as well as furniture and walls off-gassing from previous
exposure to higher levels of contamination.
Please note that your MiracleAir™ unit is equipped
with a variable speed controller. If you are running
your unit on medium blower speed, you can increase
the blower speed to compensate for the filter plugging
with contaminant. If you are operating your unit on the
maximum speed setting and your airflow is reduced,
you will need to replace the primary particle filter.
CLEANING THE PREFILTER
The prefilter is removed from the air cleaner by
opening the intake grille. Push the two buttons on the
grille and guide the grille to the open position, the grille
will hang down towards the floor on its hinges.
Shake out or vacuum the accumulated contaminants
from the prefilter. If necessary, the prefilter can be
soaked in an alkaline detergent solution. Do not soak
in an acid detergent solution or use high-pressure
water, air or steam to clean the prefilter. Doing so will
damage the prefilter and shorten its life.
REPLACING THE PARTICLE FILTER
The particle filter is removed from the air cleaner by:
1. Opening the intake grille.
